BI-113823
Based on 1 Customer Validation
BI-113823 is an orally active, blood-brain barrier-permeable bradykinin B1 receptor antagonist, with a Ki value of 5.3 nM for human receptors and 13.3 nM for rat receptors. BI-113823 reduces inflammation-induced mechanical hyperalgesia, as well as the mechanical sensitivity of peripheral afferent nerves and spinal nociceptive-specific neurons. BI-113823 alleviates liver fibrosis and portal hypertension, and improves survival in chronic liver disease models. BI-113823 inhibits the activities of monocytes, neutrophils and hepatic stellate cells, as well as the PI3K/Akt signaling pathway. BI-113823 can be used in research related to inflammatory pain, liver fibrosis and portal hypertension.
